To all whom it may concern:

Be it known that I, J0me Muss, a citizen of the United States, and a resident of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Steam- Generating Ap aratus, of which the following is a specilicati n.

Th s invention relates to steam nerati apparatus. Its object is the pr uction o a boiler with a plurality of drums and tubes connected therewith, which are all inclosed within one boiler setting referably devoid of brid walls. The num r of drums with their tu can be increased to any amount, thereby securing steam enerating apparatus of any desired capaci y. Partitions are located between someof the tubes, by means of which" the directions "of the gases and products of combustion are divided, so that portions of said gases and the like take horizontal directions, and other portions take up .and down directions.

Tubes connect up r drums in the boiler over which is locate a movable cover in the nature of a damper, by means of which other tubes above those just specified may or may not be exposed to the intense heat of the gases. Vertical tubes connect the drums l\ the boilers which are located in rows consisting of one or more lines which are ac arated from each other, and arranged so t at the tubes will be at ered when viewed in direcr tions perpendicu ax to the lonFitudinal axes of their drums, and are at tie same time located in parallel lines oblique to the longitudinal axes of the said drums. The invention is further characterized with isolated feed chambers in some of the bottoni drums, isolated steam chambers in some of the upper drums, furnaces which can fired from opposite sides, rollers sup orti each pair 0 drums with its tubes to al ow for expansion -a novel arrangement of blow oll' piping, am

other novel features described hereinafter.-

panying drawi in which Figure 1 shoag a front view of a boiler and i a partial section as on the line 1, 1 of Fi 2,

' The invention is exemplified in the accom- The invention is shown comprising a boiler with the side walls 10 and end walls 11, within which are located the upperdrums 20, 21 22 lower drums 23, 24, 25. The pairs of end drums 20, 23 and 22, 25 are connected b the outer nests of tubes 26 and 27, and t e I central nests 28. The central pair of drums preferably less than the distance between the pairs of rows. To be more s ecific the vertical planes passing throng the oblique rows ol' tubes are inclined to the vertical planes assing thro h the longitudinal axes of the ru'm's with w fiich they are,connected.

he inclinations of the planes i-of the axial lines of the tubes secures the'q'tagg'eri of tubes when viewed in directions perpen icular to the axes of thedrums.

The oblique parallel rows allow their easy cleanin and replacement if necessary. The

flow of t e gases of the furnace being at right angles to the longitudinal axes of the drums, secures with the staggered and obli uc rows of tubes, the mcirclement of the tu es with the ases. cater in rows parallel to the longitudinal axes of the drums, and this disposition allows the easy insertion of baffles or partitions between the tubes in the said parallel r'ows. Partitions 40, 41 and 42 are shown in the nests 26,

The tubes are at same time 10- 27, 28 in longitudinal rows, joining the oblique rows, which latter have clear in clined assages between them. Partitions 32 are ocated between the alternate tubes 31 that connect the central pair of drums. The said partitions form secondarv chainhere 83, 34 with the nests of tubes. The" said partitions are preferably' located in the spaces in the said rows parallel to the lon tudinal axes of the drums that separate t e pairs of tubes, and which spaces are somewhat greatcr than the distances between each pair of tubes in s 'd rows parallcl to the lon 'itudinal axes of t e drums.

The cover plate covers the tubes 45, and openings 49 are formed in the side walls for the cover plates. At one end of said latcs thcreextends the screw 50, havin t is collar 51, which is held by the cap 52-. he threads of the screw engage with a threaded cap 53, attached to end wall 11 of the boiler.

The lower drums 23', 24 and nected by the horizontal constitute the grates of t e furnace or grate bars 56 are supported on the same. In one or both of the lower drums 23 and 25 there is secured an isolated feed chamber 60, preferabl with a removable bonnet 61, into whic enter some of the tubes of the nestg26, constituting the feed water tubes. One or and 97 enter the chambers 60.
